N,N-Diethylhydroxylamine

N,N-Diethylhydroxylamine (DEHA, CAS 3710-84-7) is a secondary hydroxylamine compound supplied as a clear liquid. It is also referred to as N-Hydroxydiethylamine and Hydroxylamine,N,N-diethyl-, and carries EC number 223-055-4. No E-code designation applies to this substance.

In plastics and polymer manufacturing, DEHA functions as a radical scavenger, intercepting peroxy radicals to inhibit oxidative degradation during processing and storage. In industrial water treatment and boiler feed systems, it acts as an oxygen scavenger, reacting directly with dissolved oxygen to prevent corrosion. In oil and gas applications, it serves as a polymerization inhibitor protecting monomer streams.

DEHA is available in technical grade and is registered under REACH (EC 223-055-4). It is classified and handled in accordance with applicable CLP regulations. Packaging formats typically include drums and IBC containers, with documentation available to support procurement and compliance workflows. HS code 29280090 applies for import and export purposes.
